python3.4+mysql

在python3.4中不能用mysqldb连接mysql，可以使用pymysql完成连接mysql数据库

去github：https://github.com/PyMySQL/PyMySQL上下载pymysql的安装包pymysql
解压到某个盘符下
打开cmd窗口（win环境下），进入pymysql的根目录下执行命令，python setup.py install
在程序里，导入pymysql

import pymysql
 
conn = pymysql.connect(host='127.0.0.1', port=3306, user='root', passwd='root', db='mysql',charset="utf8")
 
cur = conn.cursor()
 
cur.execute("SELECT Host,User FROM user") 
 
print(cur.description)
 
print()
 
for row in cur:
   print(row) 
 
cur.close() 
conn.close()
